Tow truck hydraulic arm conceals 50 pounds of marijuana

The rear hydraulic arm of a tow truck was torn apart to reveal 50 pounds of marijuana at the San Ysidro Port of Entry Saturday morning.

The unusual hiding place, sniffed out by a detector dog and an imaging system, held 41 packages of marijuana worth $30,000. The 36-year-old driver, a Mexican citizen, is being held in the San Diego County Jail.
